(((hugs))), I'm sorry that you've crashed from coming off the steroids. That's a common problem for all of us. Did you do a taper or just come off the 40mg?
I hope that the flare resolves itself w/o you having to go back on prednisone. Try to rest as much as you can, and I hope you feel better soon.
